Re chamber Blaser Barrel

[paulT]

Has anyone info on rechambering of blaser Lrs2 barrels, They only produce a 1 in 8 twist in 6mmbr and i am looking to get barrel re chamberd in 243win, the factory will not do any work like rechambering unless for 24 barrels or more so im stuffed there, Im also thinking that after rechambering would there be enough room from lands for seating out the 115 dtacs, Im going to see if it is possible to do as i think that the 243 with its larger case capacity would have an edge over 6mmbr at 600 and 1000y loaded with 105 scenars or 115 dtacs, what do you think? paul T Ireland.

Blaser barrels are nitrated so they have a very hard surface.
Maybe you can cut through using a carbide reamer.
Maybe it's better if you go with the 243 ackley . I think the lesser body taper is going to clean up the excisting BR chamber better.
